So there I was, working on a project to duplicate a database from a volume copy at the storage level with the database being shutdown.
Sounds pretty simple right? Wrong! Put the database on ASM and it becomes complicated and convoluted.
Volume1 has ASM disk group in the fashion +DG1/db01/datafile, +DG1/db01/onlinelog +DG1/db01/tempfile
Volume1 will be copied to Volume2 at the storage level. What happens to all the ASM disk group?
The ASM disk group will need to be renamed using renamdg. Great! (with a little sarcasm)
So now the ASM disk groups will be +DG2/db01/datafile, +DG2/db01/onlinelog +DG2/db01/tempfile
What’s wrong with that picture?
Given I am an ASM noob, I did reach out to other and still waiting for a respond I can be confident with.
Now, if the database was not on ASM, I would be done with the project already.
1 hour to create a test case without using ASM, 8 hours too create action plan using ASM and still not completed.
